WebCarboxylic acid salts or carboxylate salts are organic compounds that have a -C(=O)O- anionic group in them. Carboxylate salts have the general formula M(RCOO) n , where M is a metal or a cation like ammonium. The negative charge delocalizes between the oxygen atoms. Carboxylic acid salts are extensively used in the preparation of buffer solutions. WebHowever when the ammonium carboxylate salt is heated to a temperature above 100 o C water is driven off and an amide is formed. General Reaction Going from reactants to products simply Conversion of Carboxylic acids to amide using DCC as an activating agent
WebThe carboxylic acid is first converted into an ammonium salt which then produces an amide on heating. The ammonium salt is formed by adding solid ammonium carbonate to an …
